Hi @Mrityunjay From the original error, did you check the folder ids as
previously mentioned earlier, do their folder Ids exist? As for the
relation, what type of cardinality do you want in tourHistory, could you
check the nms:recipient data schema and find the tourHistory relation
defined in the "Preview " tab? If you don't specify a reverse
cardinality in the recipient link, you might not have the right
cardinality in nms:recipient, same for tourReference... the links there
should be external ...
